Charisma 18: Like in any RPG worth its salt, charisma is your most important attribute.
During the late-game this attribute will save you from dying in places like Korriban when you're getting hit with force stun and insanity every other turn.
Wisdom 16: This is a late-game attribute, but it is best leveled up early on because all of your force powers and resistances depend on this attribute.
Alternatively, you can put all your points from dexterity into intelligence for that extra buff to skill points.
Intelligence 10: We want to offset the negative debuff on intelligence because losing skill points every level up really hurts in the long-run.
Items offset the need for any points in constitution. You'll be easier to kill, but there are enough items in the game to keep you alive through any situation.
Constitution 8: If you play the game properly, searching every nook and cranny, you shouldn't need any points in constitution.
You'll be offering yourself a few dexterity saves early-game, and that can make all the difference between life and death.
Dexterity 10: The main reason to put any points into this is to offset the negative debuff for putting any less.
Alternatively you can take all your points out of dexterity and put them in strength for a more easygoing early-game.
Strength 8: Though this is going to make your early-game experience relatively difficult, it is going to allow you to put more skills elsewhere that'll make late game a cinch.
